Plot

An 1840s British surgeon, Dr. Thomas Bolton, experiments with anesthetic gases in an effort to make surgery pain-free. While doing so, his demonstration before a panel of his peers ends in a horrific mishap with his patient awakening under the knife; he is forced to leave his position in disgrace. To complicate matters, he becomes addicted to the gases and gets involved with a gang of criminals, led by Black Ben and his henchman Resurrection Joe. Unfortunately, this shady partnership leads Bolton to further ruin, culminating in his unwitting participation in murder, for which he becomes the first victim of a blackmail scheme.
